The small Indian mongoose (Herpestes auropunctatus) is an invasive species in Okinawa and Amami-Oshima, Japan. Major strategies for their eradication have been the use of baited traps, which suffer from decreasing efficiency with declining populations and the bycatch of native animals. To address these concerns, mongoose-specific lures are required. In this study, we aimed to identify species- and/or sex-specific compounds from anal sac secretions of small Indian mongooses. Volatile compounds

In addition to several fatty acids, 2-phenylethanol was identified as a minor compound, which is uncommon in mammalian secretions but a dominant odorant in roses. Female samples emitted higher levels of 2-phenylethanol than male samples did. These findings indicate that 2-phenylethanol is a female-specific volatile compound of anal sac secretions in small Indian mongooses, and it may be useful as an ingredient of mongoose-specific scent lures. 2-Phenylethanol is an indicator of female anal sac secretions in small Indian mongooses.
